Aga Khan University, Pakistan.

Extracorporeal shock wave lithotripsy (ESWL) is among the most widely used modalities for treatment of urolithiasis since its introduction in the 1980s. The non-invasive technique reduces the risk of post-procedure complications and produces excellent stone free rates. However, complications may still follow and albeit rare, there are reports in literature of abscess formation post ESWL. Read More

Holmium:yttrium-aluminum-garnet laser induced lithotripsy: in-vitro investigations on fragmentation, dusting, propulsion and fluorescence.

Biomed Opt Express 2018 Nov 2;9(11):5115-5128. Epub 2018 Oct 2.

Laser-Forschungslabor, LIFE-Zentrum, University Hospital of Munich, Munich, Germany.

The fragmentation efficiency on Bego artificial stones during lithotripsy and the propulsive effect (via video tracking) was investigated for a variety of laser settings. A variation of the laser settings (pulse energy, pulse duration, repetition rate) altered the total application time required for stone fragmentation, the stone break up time, and the propulsion. The obtained results can be used to develop lithotripsy devices providing an optimal combination of low stone propulsion and high fragmentation efficacy, which can then be evaluated in a clinical setting.

Does Previous Failed Shockwave Lithotripsy Treatment Have an Influence on Retrograde Intrarenal Surgery Outcome?

J Laparoendosc Adv Surg Tech A 2018 Nov 10. Epub 2018 Nov 10.

Background: The prevalence of urolithiasis is nearly 20% and patients with urolithiasis constitute an essential part of the patients referred to the urology clinic. Many parameters should be considered for the management of renal stones and authors recommend extracorporeal shockwave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), and percutaneous nephrolithotripsy (PNL), as treatment options. Among these techniques, SWL does not require general anesthesia, has 89% success rate for renal pelvic stones: 83% for upper caliceal stones, 84% for middle caliceal stones, and 68% for lower caliceal stones.

The use of intravascular lithotripsy for the treatment of severely calcified lower limb arterial CTOs.

Authors:
Andrew Holden

J Cardiovasc Surg (Torino) 2018 Oct 31. Epub 2018 Oct 31.

Auckland City Hospital, Auckland, New Zealand -

The endovascular management of complex lower limb arterial occlusive disease is generally associated with poorer acute results, a higher incidence of provisional stenting and subsequent restenosis compared to more simple arterial lesions. Even more challenging results can be expected when two complex features are combined such as chronic total occlusion (CTO) and severe calcification. Intravascular lithotripsy (IVL) with the Shockwave system has recently been evaluated as a familiar angioplasty balloon based but effective technique for the management of arterial calcification.

Biliary and pancreatic lithotripsy devices.

VideoGIE 2018 Nov 26;3(11):329-338. Epub 2018 Sep 26.

Background And Aims: Lithotripsy is a procedure for fragmentation or destruction of stones to facilitate their removal or passage from the biliary or pancreatic ducts. Although most stones may be removed endoscopically using conventional techniques such as endoscopic sphincterotomy in combination with balloon or basket extraction, lithotripsy may be required for clearance of large, impacted, or irregularly shaped stones. Several modalities have been described, including intracorporeal techniques such as mechanical lithotripsy (ML), electrohydraulic lithotripsy (EHL), and laser lithotripsy, as well as extracorporeal shock-wave lithotripsy (ESWL).

Predictors of failure of endoscopic retrograde cholangiography in clearing bile duct stone on the initial procedure.

Saudi J Gastroenterol 2018 Oct 31. Epub 2018 Oct 31.

Gastroenterology Division, King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia.

Background/aims: The aim of this study is to predict cases where the clearance of the biliary system from stones at the initial endoscopic retrograde cholangiopancreatography (ERCP) might be of value for better risk-stratifying patients. We attempted to identify factors that are associated with a higher failure rate of clearing the biliary system on the index ERCP.

Patients And Methods: This is a retrospective study from January 2008 to January 2015. Read More

Perioperative and Periprocedural Care of Patients With Intrathecal Pump Therapy.

Neuromodulation 2018 Oct 31. Epub 2018 Oct 31.

Anesthesiology Department, University of Wisconsin School of Medicine and Public Health, Madison, WI, USA.

Introduction: There are an ever-increasing number of patients who have implanted devices for targeted delivery of drug therapy to the intrathecal space for the management of spasticity or chronic pain. This leads to a growing number of people with implanted pumps presenting for procedures and surgeries, yet there is a paucity of consolidated information available to describe the appropriate precautions and patient management during this period.

Methods: This was a systematic review to provide a summary of existing literature on intrathecal drug delivery system (IDDS) management in the perioperative and procedural period, and to highlight additional areas that require further research. Read More

Shock Wave Lithotripsy is More Effective for Residual Fragments after Percutaneous Nephrolithotomy than for Primary Stones of the Same Size: A Matched Pair Cohort Study.

Curr Urol 2018 Oct 30;12(1):27-32. Epub 2018 Jun 30.

Department of Urology, Shiraz University of Medical Sciences, Shiraz, Iran.

Aims: To compare the outcome of shock wave lithotripsy (SWL) on post-percutaneous nephrolithotomy (PCNL) residual fragments (RFs) versus primary stones of the same size through a matched pair study.

Methods: Patients with a single 5-15 mm fragment 3 months after PCNL were enrolled (study group n = 59). The control group (n = 67) consisted of all adult patients with a single 5-15 mm renal stone. Read More

Pancreatoscopy in endoscopic treatment of pancreatic duct stones, systematic review.

Minerva Chir 2018 Oct 29. Epub 2018 Oct 29.

Department of General Internal Medicine and Gastroenterology, Evangelisches Krankenhaus Düsseldorf, Düsseldorf, Germany -

Introduction: Treatment of chronic calcifying pancreatitis is challenging and requires an interdisciplinary approach including endoscopist, surgeon and radiologist. With advances in endoscopic technology therapeutic interventions in the pancreatic duct became available. ESWL is still recommended to be first line treatment, hence peroral pancreatoscopy (POP) guided intracorporal lithotripsy is a promising supplement in endoscopic therapy especially if ESWL is unsuccessful or not available.

Perceptions and Practice Patterns of Holmium Laser Goggles in Endourological Procedures: An Unnecessary Evil?

J Endourol 2018 Nov 29. Epub 2018 Nov 29.

1 Division of Urology, Department of Surgery, University of Ottawa, Ottawa, Ontario, Canada.

Purpose: The holmium laser is used increasingly for a wide array of urological procedures. Laser safety goggles are mandatory at many centers for individuals within the nominal hazard zone, as set out by the institution. Recent ex vivo studies suggest standard eye wear may be equally as protective. Read More
